Help to save on air conditioning costs

Proper maintenance is key to keeping your rooftop air conditioner (RTU) running efficiently. When you sign up for RTUsaver, we’ll recommend the best ways to optimize your system and install a FREE Wi-Fi® enabled thermostat to help you better manage cooling costs.

How does RTUsaver work?

Schedule a FREE rooftop unit checkup

A qualified professional will assess your unit to ensure it's in good repair. If over two years old, we may recommend repairs or upgrades to help save you energy.

We’ll install a FREE Wi-Fi® enabled thermostat

Once your unit is in good repair, a qualified contractor will provide you with an energy-efficiency report and install and set up your thermostat, at no cost to you.

We’ll also help program your thermostat

We’ll create set-back schedules for your thermostat so you’re comfortable when you’re there, and saving energy when you’re not.
